Channel Title: Starfish Maths Channel Description: Hello! My name's Sara and I created Starfish Maths to bring A level Maths teaching in bitesize videos by topic. I wanted to make Maths personable, engaging and as clear as possible. I use plenty of examples and exam style questions for you to try - always watch with pen and paper and have a go yourself. I speed up the working in places to encourage you pause and play, working at your own pace. Whether these videos serve as an introduction, general practice or revision, I hope they are helpful to you. Keep practicing and enjoy! www.starfishmaths.com If you find this content helpful and would like to support me, I would be very thankful! https://www.buymeacoffee.com/starfishmaths Online personal tuition £60ph. Enquire at starfishmaths@gmail.com <video> A level mechanics - forces on a slope and friction (part 2) Description: This video builds on part 1 to explore a more complex problem of forces on a slope with friction. Hope it's helpful! https://www.buymeacoffee.com/starfishmaths www.starfishmaths.com starfishmaths@gmail.com </video> <video> A Level Mechanics - Newton's second law, mass and weight Description: This video practices using Newton's second law of kinematics, f=ma. A specific example of this distinguishes between mass and weight. Three examples are used, the last of which is on a slope. Enjoy! https://www.buymeacoffee.com/starfishmaths www.starfishmaths.com starfishmaths@gmail.com </video> <video> A Level Maths exam question on trigonometry multiple angles Description: Hello! Today we have an A level question about trigonometry, using some identities and multiple angles. Hope it's useful to you! https://www.buymeacoffee.com/starfishmaths www.starfishmaths.com starfishmaths@gmail.com </video> <video> Sin and cos rules Description: This video covers the sin and cos rules for triangles, as well as the formula for the area of a triangle. 3 exam style questions included. Enjoy! https://www.buymeacoffee.com/starfishmaths www.starfishmaths.com starfishmaths@gmail.com </video> <video> Binomial approximations Description: Following on from simple binomial expansions, this video considers when the power is not a positive integer, and a binomial expansion can be used to give an infinite series for approximation. I cover 3 examples, all exam style. Enjoy! https://www.buymeacoffee.com/starfishmaths www.starfishmaths.com starfishmaths@gmail.com </video> <video> A Level Maths exam question on integration by substitution Description: This is the first video of a more juicy exam question, shot very simply off my screen. A bit different to my usual teaching videos - let me know what you think in the comments! Is it helpful? Do you want more and if so are there any questions you would like me to look at? https://www.buymeacoffee.com/starfishmaths www.starfishmaths.com starfishmaths@gmail.com </video> <video> Geometric series Description: This video covers geometric progressions, sequences and series. We derive formulae for the general term, the sum of the series and the sum to infinity of convergent series. 3 exam style questions covered. Enjoy! https://www.buymeacoffee.com/starfishmaths www.starfishmaths.com starfishmaths@gmail.com </video> <video> Proof by contradiction Description: The second of 2 videos on proof - here we have proof by contradiction. This is a very powerful technique which involves proving that the opposite of a statement can't be true. I cover 5 examples, each full of tips and tricks which you may use again in similar problems. Enjoy! https://www.buymeacoffee.com/starfishmaths www.starfishmaths.com starfishmaths@gmail.com </video> <video> A Level Maths exam question on functions - differentiation and graph transformations Description: This A level exam question explores the graph of a function, and involves differentiation with exponentials, the product rule, finding stationary points, graph transformations, and the range of functions. Lots of skills to practice! Enjoy! https://www.buymeacoffee.com/starfishmaths www.starfishmaths.com starfishmaths@gmail.com </video> <video> A Level Mechanics - Resolving vectors on force diagrams Description: This video begins to explore basic force diagrams and resolving vectors. It assumes some knowledge of vectors, which is covered in a previous video. Questions involve finding resultant forces, and using equilibrium. Enjoy! https://www.buymeacoffee.com/starfishmaths www.starfishmaths.com starfishmaths@gmail.com </video> <video> A Level Mechanics - Forces on a slope and friction Description: This video is an introduction to managing and resolving forces on a slope. I show you how to label forces, break them into components, write equations and solve them. We use a block at rest on a rough inclined surface. Enjoy! https://www.buymeacoffee.com/starfishmaths www.starfishmaths.com starfishmaths@gmail.com </video> <video> Proof - counter examples, proof by exhaustion and direct proof Description: This is the first video on proof for A Level Maths, covering disproof by counter example, proof by exhaustion and direct proof by deduction. I use a few examples of each, including expressions for odd/even numbers, consecutive integers and rational/irrational numbers. Enjoy! https://www.buymeacoffee.com/starfishmaths www.starfishmaths.com starfishmaths@gmail.com </video> <video> A Level Mechanics - Vectors Description: This video covers the basics of vectors for A Level Maths - starting with how to draw and write them, add them, find the magnitude and direction, find vectors between coordinates, position vectors, and vectors in 3 dimensions. Hope you find something useful! Enjoy https://www.buymeacoffee.com/starfishmaths www.starfishmaths.com starfishmaths@gmail.com </video> <video> A Level Maths exam question on factor theorem, algebraic long division and integration Description: Today's exam question is from an AS paper, all about a polynomial. We use the factor theorem, long division (and I have a new method for that today) and integration to find the area under the curve. Enjoy! https://www.buymeacoffee.com/starfishmaths www.starfishmaths.com starfishmaths@gmail.com </video> <video> A Level Maths exam question on circles Description: Today's exam question is on circles. The first part is pretty standard, the second part a bit more creative. Enjoy! https://www.buymeacoffee.com/starfishmaths www.starfishmaths.com starfishmaths@gmail.com </video>
